-
The following enhancements have been made to DHCP snooping, to support
MAC-forced forwarding:
■
MAC-forced forwarding checks the DHCP snooping database to find out
which router has been assigned to each DHCP client. DHCP snooping
determines this from the router list in DHCP acknowledgement messages.
However, some clients do not request a router. DHCP snooping now modifies
request messages from such clients, to ensure that they request a router. This
enables MAC-forced forwarding to interoperate with such clients.
■
Output from the command show dhcpsnooping database now displays the
list of routers that are assigned to each client, as shown in bold in the
following example:
Current valid entries
MAC Address IP Address Expires(s) VLAN Port ID Source
